Authentication and Encryption Vulnerability in SMA Solar Technology Products

CVE-2017-9857

What is CVE-2017-9857?

A security vulnerability has been identified in the SMAdata2+ communication protocol used by SMA Solar Technology products. This issue arises due to improper authentication and lack of encryption, rendering the protocol susceptible to man in the middle, packet injection, and replay attacks. Attackers can exploit this vulnerability to intercept and manipulate communication packets, change settings, and access hidden functionalities of the system from any location within the network. Although the vendor asserts that authentication and encryption are unnecessary on isolated subnetworks, it is crucial to address these vulnerabilities to protect sensitive information and maintain system integrity.
